These newspapers run their own archive services and monetise them; hence their titles are not available free. Each newspaper does make its archive available in text searchable formats. The Times's service is divided into two, hosted separately – an archive from 1785-1985, run in partnership with Gale, and the Newstext service offering issues from 1985 on. Gale also runs the Telegraph's archive from 1855-2000. The Guardian for the period 1829-2003 and its sister paper The Observer (1791-2003) are available via the paid-for newspapers.com site, but you can opt just to pay to receive access to those two titles, rather than pay the higher cost of accessing the whole service.

By far the best source of British newspapers more generally is the British Newspaper Archive, co-ordinated by the British Library. This is also a paid-for service, but it currently offers a total of more than 15m pages. However, the archive is very much an historical one, and it offers relatively few resources dating to the 1960s and afterwards.

Costs vary. The BNA is £80 a year. Gales does not sell individual subscriptions to The Times or the Telegraph but a good number of British public libraries do subscribe to the Times archive, at least, so, if you are in the UK, you may be able to access the material that way – check. The solus Guardian/Observer archive is available for $10 a month
